Storage & handling
These compounds are photo- and temperature-sensitive; handle per standard laboratory practice.
- Lyophilized storage: Keep the sealed vials cool, dry, and protected from light. For longer-term storage, freezing is standard practice for lyophilized material.
- After reconstitution: Refrigerate (approximately 2–8 °C) and follow your institution’s SOPs for aliquoting, handling, and disposal. Avoid repeated freeze–thaw cycles.
- Diluent not included: Suitable laboratory diluent and reconstitution supplies are not provided with this product.
- UV-resistant glass vials to help protect photo-labile material during storage.
- Tamper-evident seals to support chain-of-custody and inventory controls.
Why source this stack from Sports Technology Labs
Quality control across the research-peptide industry is inconsistent, and many suppliers do not publish third-party testing for their products. Independent verification of identity and purity is essential for reproducible research.
All three compounds verified by MZ Biolabs (Tucson, AZ), an accredited US laboratory, via HPLC and mass spectrometry, with batch-linked COAs.
Each compound is freeze-dried into a sterile, UV-resistant glass vial.
Supports chain-of-custody, label transparency, and batch-linked traceability.
Transparent business, standard payment methods, no misrepresentation.
What is in the Glow Stack?
This stack, marketed as the “Glow Stack,” pairs three research compounds — BPC-157, TB-500, and GHK-Cu — supplied as separate lyophilized vials. The three are distinct molecules with different structures, described below by identity only.
BPC-157
A synthetic pentadecapeptide (15 amino acids) whose sequence corresponds to a partial fragment of Body Protection Compound (BPC), a protein identified in human gastric juice. Used as a research chemical to investigate this peptide in experimental models.
TB-500 (Thymosin β4)
A synthetic peptide analog of thymosin β4, a naturally occurring 43-amino-acid peptide. Thymosin β4 is characterized biochemically as an actin-sequestering peptide (it binds monomeric G-actin). Used as a research chemical to investigate thymosin β4 biology.
GHK-Cu
A tripeptide (Gly-His-Lys) that forms a coordination complex with copper(II), giving the characteristic blue-purple color. The tripeptide occurs naturally in human plasma. Used as a research chemical to investigate the GHK-copper complex in experimental models.
These compounds are supplied strictly as research chemicals for laboratory research. Sports Technology Labs makes no claims regarding their effects, and nothing in this listing should be interpreted as describing outcomes in humans or animals.
Important regulatory information
All three compounds are investigational research chemicals. They are not approved by the FDA and are not drugs, foods, dietary supplements, or cosmetics. Marketing them for human use is unlawful.
BPC-157 has no approval from any governmental regulatory health authority for human therapeutic use, and as such falls under WADA category S0 (Non-Approved Substances), prohibited at all times (ref. 4).
Thymosin β4 (TB-500) is associated with WADA category S2 (Peptide Hormones, Growth Factors, Related Substances and Mimetics), under growth factors affecting regenerative capacity. Athletes should consult the current WADA Prohibited List (ref. 4).
GHK-Cu is not currently listed on the World Anti-Doping Agency Prohibited List.
Sports Technology Labs are chemical suppliers, not medical providers. We do not condone or encourage consumer use of research compounds.
